CAUTION: Alerts you to a potential hazard that could cause loss of data, or damage the system or equipment.

WARNING: Alerts you to a potential hazard that could cause personal injury.

Safety Information

CAUTION: Circuit devices are sensitive to static electricity, which can damage their delicate electronics. Dry weather conditions or

walking across a carpeted floor may cause you to acquire a static electrical charge.

To protect your device, always:

• Touch the metal chassis of your computer to ground the static electrical charge before you pick up the circuit device.

• Pick up the device by holding it on the left and right edges only.

• If you need to connect this switch to an outdoor device, add an arrester on the cable between the outdoor device and this

switch.

NOTE: The switch is indoor device, if it connects with an outdoor device, then it must use a lightning arrester to protect the

switch.

WARNING:

• Do not place the switch outdoors.

• Before installation, make sure the input power supply and product specifications are compatible with each other.

• To reduce the risk of electric shock, disconnect all AC or DC power cords and RPS cables to completely remove power from the

unit.

• Before importing/exporting configuration, make sure the firmware version is the same.

• After a firmware upgrade, the switch will update automatically to the latest firmware version.

LED Condition Status

Link/ACT Green Lights when the corresponding port is in Link/ACT mode.

Speed Green Lights when the corresponding port is in Speed mode.

PoE (Link/ACT) Green Lights when the corresponding port is in PoE (Link/ACT) mode.

2.5 Switch Architecture

The switch operates at wire-speed, transporting multiple packets at low latency on all ports simultaneously.The switch also
operates at full-duplex, which effectively doubles the bandwidth of each connection.

For maximum data integrity, the switch uses store-and-forward technology. With this technology, the entire packet is received into
a buffer and checked for validity before it is forwarded. This prevents errors from being propagated throughout the network.

2.6 Network Management Options

You can also manage the switch over the network via a Web browser or Telnet. The switch includes a built-in network
management agent that allows it to be managed in-band using SNMP or RMON (Groups 1, 2, 3, 9) protocols. It also has an
RS-232 DB9 console port connector on the front panel for out-of-band management. A PC may be connected to this port for
configuration and monitoring out-of-band via a null-modem serial cable. (See Appendix B for wiring options.)

NOTE: For a detailed description of the management features, refer to the user’s manual.

3. Operation of Web-based Management

3.1 Initial Configuration

This chapter explains how to configure and manage the LPB5028A or LPB5052A through the Web user interface. You can easily
access and monitor through any one switch port the switch status, including MIBs status, each port activity, Spanning tree status,
port aggregation status, multicast traffic, VLAN and priority status, even illegal access record and so on.

The default values of the LPB5028A are listed in the table below:

IP Addres s : 192.168.1.1

Subnet Mask: 255.255.255.0

Default Gateway: 192.168.1.254

Username: admin

Password: blank

Password

After you configure the LPB5028A, you can browse to it. Type http://192.168.1.1 in the address row in a browser, and you will see
the login screen prompting you for the username and password to login and access authentication.

The default username is “admin” and password is empty. The first time you use the switch, enter the default username and pass­word, and then click on the <Login> button. The login process now is completed.

NOTE: In the login menu, you have to input the complete username and password respectively; the LPB5028A will not give you a

shortcut to username automatically. This looks inconvenient, but is safer.

This supports a simple user management function allowing only one administrator to configure the system at a time. If two or
more users are using administrator’s identity, it will allow only the one who logs in first to configure the system. The rest of the
users, even with administrator’s identity, can only monitor the system. Users who have no administrator’s identity can only moni­tor the system, and a maximum of three users can login simultaneously to the LPB5028A or LPB5052A.

NOTE: When you login to the switch to manage it, you must first type the username, which, by default, is admin. The password is

blank, so after you type admin, press enter. The Web management page will appear.

You can manage the LPB5028A or LPB5052A switch Web UI via both ipv4 and ipv6. To optimize the display effect, we
recommend you use Microsoft IE 6.0 and above, Netscape V7.1 and above, or FireFox V1.00 and above with 1024 x 768
resolution. The switch supports a neutral Web browser interface.

NOTE: To enable the DHCP function, if you don’t have a DHCP server to provide IP addresses to the switch, use the switch’s

default IP address: 192.168.1.1.

Connecting to Network Devices

The switch is designed to connect to 10-, 100-, or 1000-Mbps network cards in PCs and servers, as well as to other switches and
hubs. You can also connect it to remote devices using optional SFP transceivers.

Twisted-Pair Devices

Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category 5, 5e, or 6 cable
for 1000BASE-T connections, and Category 5 or better for 100BASE-TX connections.

Cabling Guidelines

The RJ-45 ports on the switch support automatic MDI/MDI-X pin-out configuration, so you can use standard straight-through
twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).

See Appendix B for further information on cabling.

CAUTION: Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with

RJ-45 connectors that conform to FCC standards.

3.2 Connecting to PCs, Servers, Hubs, and Switches

STEP 1: Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.

STEP 2: If the device is a network card and the switch is in the wiring closet, attach the other end of the cable segment to a
modular wall outlet that is connected to the wiring closet. (See the “Network Wiring Connections” section.) Otherwise, attach
the other end to an available port on the switch.

Make sure each twisted-pair cable does not exceed 328 feet (100 meters) in length.

NOTE: Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise, back

pressure jamming signals may degrade overall performance for the segment attached to the hub.

STEP 3: As each connection is made, the Link LED (on the switch) corresponding to each port will light green (1000 Mbps) or
amber (100 Mbps) to indicate that the connection is valid.

3.3 Network Wiring Connections

Today, the punch-down block is an integral part of many of the newer equipment racks. It is actually part of the patch panel.
Instructions for making connections in the wiring closet with this type of equipment follow.

STEP 1: Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel.

STEP 2: If not already in place, attach one end of a cable segment to the back of the patch panel where the punch-down block is
located, and the other end to a modular wall outlet.

is from -720 to 720 minutes

Page 24

Figure 4-4. Time configuration screen.

724-746-5500 | blackbox.com

Chapter 4: System

• Daylight Saving: Daylight saving is adopted in some countries. If set, it will adjust the time lag or in advance in unit of hours,

according to the starting date and the ending date. For example, if you set the day light saving to be 1 hour, when the time
passes over the starting time, the system time will be increased one hour after one minute at the time since it passed over. And
when the time passes over the ending time, the system time will be decreased one hour after one minute at the time since it
passed over.

The valid configurable daylight saving time supported by the switch is –5 – +5 step one hour. It does not have to adjust current

time, and you don’t have to set the starting/ending date. If you set daylight saving to be non-zero, you have to set the starting/
ending date as well; otherwise, the daylight saving function will not be activated.

• Time Set Offset: Provide the Daylight saving time set offset. The offset is given in minutes east of GMT. The valid range is from

1 to 1440 minutes. default is 60 mins.

• Daylight Savings Type: Provide the Daylight savings type selection. You can select “ By Dates” or “Recurring” two type for

Daylight saving type.

• From: To configure date and time when Daylight savings starts, the format is “YYYYMM-DD HH:MM.”

• To: To configure date and time when Daylight savings ends, the format is “YYYY-MMDD HH:MM.”

NOTE: The “from” and “to” fields display the “From” and “To” field information you set.

4.2.2 NTP

NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean Time (GMT). Use the NTP mode to
select a built-in NTP time server or to manually specify a user-defined NTP server as well as Time Zone. The switch will sync the
time after you press the <Apply> button. Though it synchronizes the time automatically, NTP does not update the time
periodically without a user’s processing.

Time Zone is an offset time off GMT. You have to select the time zone first and then perform time sync via NTP because the
switch will combine this time zone offset and updated NTP time to display the local time; otherwise, you will not able to get the
correct time. The switch supports a configurable time zone from –12 to +13 step 1 hour.

Default Time zone: +8 Hrs.

Web Interface

To configure Time in the Web interface:

1. Click SYSTEM, NTP.

• Password (again): Type the password again. You must type the same password again in the field.

• Privilege Level: The privilege level of the user. The allowed range is 1 to 15. If the privilege level value is 15, it can access all

groups; i.e., it is granted the full control of the device. But other values need to refer to each group privilege level. A user's privi­lege should be same or greater than the group privilege level to have the access to that group. By default, most groups privilege
level 5 has read-only access and privilege level 10 has read-write access. And the system maintenance (software upload, factory
defaults, and etc.) need user privilege level 15. Generally, the privilege level 15 can be used for an administrator account, privi­lege level 10 for a standard user account and privilege level 5 for a guest account.

• Privilege Levels: Every group has an authorization Privilege level for the following sub groups: configuration read-only,

configuration/execute read-write, status/statistics read-only, status/statistics read-write (e.g. for clearing of statistics). User
Privilege should be same or greater than the authorization Privilege level to have access to that group.

4.4 IP

IP is an acronym for Internet Protocol. It is a protocol used for communicating data across an internet network.

IP is a “best effort” system, which means that no packet of information sent over is assured to reach its destination in the same
condition it was sent. Each device connected to a Local Area Network (LAN) or Wide Area Network (WAN) is given an Internet
Protocol address, and this IP address is used to identify the device uniquely among all other devices connected to the extended
network.

The current version of the Internet protocol is IPv4, which has 32-bit Internet Protocol addresses, allowing for in excess of four bil­lion unique addresses. This number is reduced drastically by the practice of webmasters taking addresses in large blocks, the bulk
of which remain unused. There is a rather substantial movement to adopt a new version of the Internet Protocol, IPv6, which
would have 128-bit Internet Protocol addresses. This number can be represented roughly by a three with thirty-nine zeroes after
it. However, IPv4 is still the protocol of choice for most of the Internet.

4.4.1 IPV4

The IPv4 address for the switch could be obtained via DHCP Server for VLAN 1. To manually configure an address, you need to
change the switch's default settings to values that are compatible with your network. You may also need to a establish a default
gateway between the switch and management stations that exist on another network segment.

Configure the switch-managed IP information on this page.

The Configured column is used to view or change the IP configuration.

The Current column is used to show the active IP configuration.

4.6 SNMP

Any Network Management System (NMS) running the Simple Network Management Protocol (SNMP) can manage the Managed
devices equipped with an SNMP agent, provided that the Management Information Base (MIB) is installed correctly on the man­aged devices. The SNMP is a protocol that is used to govern the transfer of information between SNMP manager and agent and
traverses the Object Identity (OID) of the management Information Base (MIB), described in the form of SMI syntax. SNMP agent
is running on the switch to respond to the request issued by SNMP manager.

Basically, it is passive except when issuing the trap information. The switch supports a switch to turn on or off the SNMP agent. If
you set the SNMP field to “Enable,” the SNMP agent will start up. All supported MIB OIDs, including RMON MIB, can be accessed
via SNMP manager. If the SNMP field is set to “Disable,” the SNMP agent will be de-activated, and the related Community Name,
Trap Host IP Address, Trap, and all MIB counters will be ignored.

4.6 .1 Syst em

This section describes how to configure an SNMP System on the switch. This function is used to configure SNMP settings, com­munity name, trap host, and public traps, as well as SNMP throttle. An SNMP manager must pass the authentication by identify­ing both community names, then it can access the MIB information of the target device. So, both parties must have the same
community name. Once you complete the setting, click the <Apply> button, and the setting takes effect.

into EtherTypes. IPv4, ARP protocol, MAC and VLAN parameters etc. Here we will just go over the standard and extended access
lists for TCP/IP. As you create ACEs for ingress classification, you can assign a policy for each port. The policy number is 1–8; how­ever, each policy can be applied to any port. This makes it very easy to determine what type of ACL policy you will be working
with.

5.2.1 Ports

The section describes how to configure the ACL parameters (ACE) of each switch port. These parameters will affect frames
received on a port unless the frame matches a specific ACE.

Web Interface

To configure the ACL Ports Configuration in the web interface:

1. Click Configuration, ACL, then Ports.

2. Scroll to the specific parameter value to select the correct value for port ACL setting.

3. Click on Apply to save the setting.

4. If you want to cancel the setting, then you need to click the reset button. It will revert to previously saved values.

5. After you finish configuring settings, then you can see the port Counter. Click refresh to update the counter or Clear the
information.

5.2.3 Access Control List

The section describes how to configure Access Control List rule. An Access Control List (ACL) is a sequential list of permit or deny
conditions that apply to IP addresses, MAC addresses, or other more specific criteria. This switch tests ingress packets against the
conditions in an ACL one by one. A packet will be accepted as soon as it matches a permit rule, or dropped as soon as it matches
a deny rule. If no rules match, the frame is accepted. Other actions can also be invoked when a matching packet is found,
including rate limiting, copying matching packets to another port or to the system log, or shutting down a port.

5.3 Aggregation

Aggregation is used to configure the settings of Link Aggregation. You can bundle more than one port with the same speed, full
duplex, and the same MAC to be a single logical port, thus the logical port aggregates the bandwidth of these ports. This means
you can apply your current Ethernet equipment’s settings to build the bandwidth aggregation. For example, if there are three Fast
Ethernet ports aggregated in a logical port, then this logical port has bandwidth three times as high as a single Fast Ethernet port
has.

5.3.1 Static Trunk

The Aggregation Configuration is used to configure the settings of Link Aggregation. You can bundle more than one port with
the same speed, full duplex and the same MAC to be a single logical port, thus the logical port aggregates the bandwidth of
these ports. This means you can apply your current Ethernet equipment’s to build the bandwidth aggregation.

Static Trunk

Ports using Static Trunk as their trunk method can choose their unique Static GroupID to form a logical trunked port.” The benefit
of using the Static Trunk method is that a port can immediately become a member of a trunk group without any handshaking
with its peer port. This is also a disadvantage because the peer ports of your static trunk group may not know that they should
be aggregated together to form a “logical trunked port.” Using Static Trunk on both ends of a link is strongly recommended.

NOTE: Low speed links will stay in a “not ready” state when using static trunk to aggregate with high speed links.

Web Interface

To configure the Trunk Aggregation Hash mode and Aggregation Group in the web interface:

1. Click Configuration, Static Trunk, and then Aggregation Mode Configuration.

2. Evoke to enable or disable the aggregation mode function. Select Aggregation Group ID and Port members.

3. Click the apply to save the setting.

4. If you want to cancel the setting then you need to click the reset button. It will revert to previously saved values.

5.3.2 LACP

Ports using Link Aggregation Control Protocol (according to IEEE 802.3ad specification) as their trunking method can choose their
unique LACP GroupID to form a logic “trunked port.” The benefit of using LACP is that a port makes an agreement with its peer
port before it becomes a ready member of a “trunk group” (also called aggregator). LACP is safer than the other trunking
method—static trunk.

Configuration

This page allows the user to inspect the current LACP port configurations, and possibly change them as well An LACP trunk
group with more than one ready member-ports is a “real trunked” group. An LACP trunk group with only one or less than one

5.4 Spanning Tree

The Spanning Tree Protocol (STP) can be used to detect and disable network loops, and to provide backup links between
switches, bridges, or routers. This allows the switch to interact with other bridging devices (that is, an STP-compliant switch,
bridge, or router) in your network to ensure that only one route exists between any two stations on the network, and provide
backup links that automatically take over when a primary link goes down.

Page 68

Figure 5-15. The LACP Statistics screen.

724-746-5500 | blackbox.com

Chapter 5: Configuration

STP - STP uses a distributed algorithm to select a bridging device (STP- compliant switch, bridge, or router) that serves as the root
of the spanning tree network. It selects a root port on each bridging device (except for the root device) which incurs the lowest
path cost when

forwarding a packet from that device to the root device. Then it selects a designated bridging device from each LAN which incurs
the lowest path cost when forwarding a packet from that LAN to the root device. All ports connected to designated bridging
devices are assigned as designated ports. After determining the lowest cost spanning tree, it enables all root ports and designated
ports, and disables all other ports. Network packets are therefore only forwarded between root ports and designated ports, elimi­nating any possible network loops.

Figure 5-16. Spanning Tree example.

Once a stable network topology has been established, all bridges listen for Hello BPDUs (Bridge Protocol Data Units) transmitted
from the Root Bridge. If a bridge does not get a Hello BPDU after a predefined interval (Maximum Age), the bridge assumes that
the link to the Root Bridge is down. This bridge will then initiate negotiations with other bridges to reconfigure the network to
reestablish a valid network topology.

Chapter 5: Configuration

Figure 5-17. STP Bridge Configuration screen.

Parameter description:

Basic Settings

• Protocol Version: The STP protocol version setting. Valid values are STP, RSTP, and MSTP.

• Bridge Priority: Controls the bridge priority. Lower numeric values have higher priority. The bridge priority plus the MSTI instance

number, concatenated with the 6-byte MAC address of the switch, forms a Bridge Identifier. For MSTP operation, this is the
priority of the CIST. Otherwise, this is the priority of the STP/RSTP bridge.

• Forward Delay: The delay used by STP Bridges to transmit Root and Designated Ports to Forwarding (used in STP compatible

mode). Valid values are in the range 4 to 30 seconds.

• Max Age: The maximum age of the information transmitted by the Bridge when it is the Root Bridge. Valid values are in the

range 6 to 40 seconds, and MaxAge must be <= (FwdDelay-1)*2.

• Maximum Hop Count: This defines the initial value of remaining Hops for MSTI information generated at the boundary of an

MSTI region. It defines how many bridges a root bridge can distribute its BPDU information to. Valid values are in the range 6 to
40 hops.

• Transmit Hold Count: The number of BPDUs a bridge port can send per second. When exceeded, transmission of the next BPDU

will be delayed. Valid values are in the range 1 to 10 BPDUs per second.

Advanced Settings

• Edge Port BPDU Filtering: Control whether a port explicitly configured as Edge will transmit and receive BPDUs.

• Edge Port BPDU Guard: Control whether a port explicitly configured as Edge will disable itself upon reception of a BPDU. The

port will enter the error-disabled state, and will be removed from the active topology.

• Port Error Recovery: Control whether a port in the error-disabled state automatically will be enabled after a certain time. If

recovery is not enabled, ports have to be disabled and re-enabled for normal STP operation. The condition is also cleared by a
system reboot.

Page 70

Chapter 5: Configuration

Parameter description:

• Port: The switch port number of the logical STP port.

• STP Enabled: Controls whether STP is enabled on this switch port.

• Path Cost: Controls the path cost incurred by the port. The Auto setting will set the path cost as appropriate by the physical link

speed, using the 802.1D recommended values. Using the Specific setting, a user-defined value can be entered. The path cost is
used when establishing the active topology of the network. Lower path cost ports are chosen as forwarding ports in favor of
higher path cost ports. Valid values are in the range 1 to 200000000.

• Priority: Controls the port priority. This can be used to control priority of ports having identical port cost. (See above).

Chapter 5: Configuration

• operEdge (state flag): Operational flag describing whether the port is connecting directly to edge devices. (No Bridges

attached). Transition to the forwarding state is faster for edge ports (having operEdge true) than for other ports.The value of
this flag is based on AdminEdge and AutoEdge fields. This flag is displayed as Edge in Monitor->Spanning Tree -> STP Detailed
Bridge Status.

• AdminEdge: Controls whether the operEdge flag should start as set or cleared. (The initial operEdge state when a port is

initialized).

• AutoEdge: Controls whether the bridge should enable automatic edge detection on the bridge port. This allows operEdge to be

derived from whether BPDUs are received on the port or not.

• Restricted Role: If enabled, this causes the port not to be selected as Root Port for the CIST or any MSTI, even if it has the best

spanning tree priority vector. Such a port will be selected as an Alternate Port after the Root Port has been selected. If set, it can
cause lack of spanning tree connectivity. It can be set by a network administrator to prevent bridges external to a core region of
the network from influencing the spanning tree active topology, possibly because those bridges are not under the full control of
the administrator. This feature is also known as Root Guard.

• Restricted TCN: If enabled, this causes the port not to propagate received topology change notifications and topology changes

to other ports. If set, it can cause temporary loss of connectivity after changes in a spanning tree's active topology as a result of
persistently incorrect learned station location information. It is set by a network administrator to prevent bridges external to a
core region of the network from bridging, causing address flushing in that region, possibly because those bridges are not under
the full control of the administrator or the physical link state of the attached LANs transmits frequently.

• BPDU Guard: If enabled, causes the port to disable itself upon receiving valid BPDUs. Contrary to the similar bridge setting, the

port Edge status does not affect this setting. A port entering error-disabled state due to this setting is subject to the bridge Port
Error Recovery setting as well.

• Point to Point: Controls whether the port connects to a point-to-point LAN rather than to a shared medium. This can be

automatically determined, or forced either true or false. Transition to the forwarding state is faster for point-to-point LANs than
for shared media.

Apply: Click to apply changes.

Reset: Click to undo any changes made locally and revert to previously saved values.

5.4.5 MSTI Ports

5.5 IGMP Snooping

The function is used to establish the multicast groups to forward the multicast packet to the member ports. It avoids wasting the
bandwidth while IP multicast packets are running over the network. A switch that does not support IGMP or IGMP Snooping can
not tell the multicast packet from the broadcast packet, so it can only treat them all as broadcast packets. Without IGMP
Snooping, the multicast packet forwarding function forwards the broadcast packets.

The switch supports IGMP Snooping. This includes query, report, and leave, which is a type of packet exchanged between an IP
Multicast Router/Switch and an IP Multicast Host. The switch can update the Multicast table when a member (port) joins or
leaves an IP Multicast Destination Address. With this function, once a switch receives an IP multicast packet, it will forward the
packet to the members who previously joined in a specified IP multicast group.

The packets will be discarded by IGMP Snooping if the user transmits multicast packets to the multicast group that had not been
built in advance. IGMP mode enables the switch to issue an IGMP function to enable IGMP proxy or snooping on the switch,
which connects to a router closer to the root of the tree. This interface is the upstream interface. The router on the upstream
interface should be running IGMP.

5.5.3 Port Group Filtering

The section describes how to set the IGMP Port Group Filtering. With the IGMP filtering feature, an user can exert this type of
control. In some network Application environments, such as metropolitan or multiple-dwelling unit (MDU) installations, a user
might want to control the multicast groups to which a user on a switch port can belong. This allows the user to control the
distribution of multicast services, such as IP/TV, based on some type of subscription or service plan.

With this feature, you can filter multicast joins on a per-port basis by configuring IP multicast profiles and associating them with
individual switch ports. An IGMP profile can contain one or more multicast groups and specifies whether access to the group is
permitted or denied. If an IGMP profile denying access to a multicast group is applied to a switch port, the IGMP join report
requesting the stream of IP multicast traffic is dropped, and the port is not allowed to receive IP multicast traffic from that group.
If the filtering action permits access to the multicast group, the IGMP report from the port is forwarded for normal processing.
IGMP filtering controls only IGMP membership join reports and has no relationship to the function that directs the forwarding of
IP multicast traffic.

Web Interface

5.5.6 IPv4 SSM information

Source Specific Multicast (SSM) is a datagram delivery model that best supports one-to-many applications, also known as
broadcast applications. SSM is a core network technology of IP multicast targeted for audio and video broadcast application
environments.

For the SSM delivery mode, an IP multicast receiver host must use IGMP Version 3 (IGMPv3) to subscribe to channel (S, G). By
subscribing to this channel, the receiver host is indicating that it wants to receive IP multicast traffic sent by source host S to group
G. The network will deliver IP multicast packets from source host S to group G to all hosts in the network that have subscribed to
the channel (S, G).

SSM does not require group address allocation within the network, only within each source host. Different applications running
on the same source host must use different SSM groups. Different applications running on different source hosts can arbitrarily
reuse SSM group addresses without causing any excess traffic on the network.

Addresses in the range 232.0.0.0/8 (232.0.0.0 to 232.255.255.255) are reserved for SSM by IANA. In the switch, you can also
configure SSM for arbitrary IP multicast addresses.

5.6 MLD Snooping

Curiously enough, a network node that acts as a source of IPv6 multicast traffic is only an indirect participant in MLD snooping—
it just provides multicast traffic, and MLD doesn’t interact with it.

NOTE: In a desktop conferencing application, a network node may act as both a source and an MLD host, but MLD interacts

with that node only in its role as an MLD host.

A source node creates multicast traffic by sending packets to a multicast address. In IPv6, addresses with the first eight bits set
(that is, “FF” as the first two characters of the address) are multicast addresses, and any node that listens to such an address will
receive the traffic sent to that address. Application software running on the source and destination systems cooperates to
determine what multicast address to use.

NOTE: This is a function of the application software, not of MLD.

When MLD snooping is enabled on a VLAN, the switch acts to minimize unnecessary multicast traffic. If the switch receives
multicast traffic destined for a given multicast address, it forwards that traffic only to ports on the VLAN that have MLD hosts for
that address. It drops that traffic for ports on the VLAN that have no MLD hosts.

5.6.1 Basic Configuration

The section will explain how to configure the MLD Snooping basic configuration and the parameters.

Web Interface

To configure the MLD Snooping Configuration in the web interface:

5.8 LLDP

The switch supports the LLDP. For current information on your switch model, The Link Layer Discovery Protocol (LLDP) provides a
standards-based method for enabling switches to advertise themselves to adjacent devices and to learn about adjacent LLDP
devices. The Link Layer Discovery Protocol (LLDP) is a vendor-neutral Link Layer protocol in the Internet Protocol Suite used by
network devices for advertising their identity, capabilities, and neighbors on a IEEE 802 local area network, principally wired
Ethernet. The protocol is formally referred to by the IEEE as Station and Media Access Control Connectivity Discovery specified in
standards document IEEE 802.1AB.

Chapter 5: Configuration

Parameter description:

LLDP Parameters

• Tx Interval: The switch periodically transmits LLDP frames to its neighbors to ensure that the network discovery information is

up-to-date. The interval between each LLDP frame is determined by the Tx Interval value. Valid values are restricted to 5–32768
seconds.

• Tx Hold: Each LLDP frame contains information about how long the information in the LLDP frame will be considered valid. The

LLDP information valid period is set to Tx Hold multiplied by Tx Interval seconds. Valid values are restricted to 2–10 times.

• Tx Delay: If some configuration is changed (e.g. the IP address) a new LLDP frame is transmitted, but the time between the LLDP

frames will always be at least the value of Tx Delay seconds. Tx Delay cannot be larger than 1/4 of the Tx Interval value. Valid
values are restricted to 1–8192 seconds.

• Tx Reinit: When a port is disabled, LLDP is disabled or the switch is rebooted, an LLDP shutdown frame is transmitted to the

neighboring units, signaling that the LLDP information isn't valid anymore. Tx Reinit controls the amount of seconds between the
shutdown frame and a new LLDP initialization. Valid values are restricted to 1–10 seconds.

LLDP Port Configuration

The LLDP port settings relate to the currently selected, as reflected by the page header.

• Port: The switch port number of the logical LLDP port.

• Mode: Select LLDP mode.

Rx only: The switch will not send out LLDP information, but LLDP information from neighbor units is analyzed.

Tx only: The switch will drop LLDP information received from neighbors, but will send out LLDP information.

Disabled :The switch will not send out LLDP information, and will drop LLDP information received from neighbors.

Enabled The switch will send out LLDP information, and will analyze LLDP information received from neighbors.

• CDP Aware: Select CDP awareness.

The CDP operation is restricted to decoding incoming CDP frames (The switch doesn't transmit CDP frames). CDP frames are

only decoded if LLDP on the port is enabled.

Only CDP TLVs that can be mapped to a corresponding field in the LLDP neighbors table are decoded. All other TLVs are

discarded (Unrecognized CDP TLVs and discarded CDP frames are not shown in the LLDP statistics.). CDP TLVs are mapped onto
the LLDP neighbors table as shown below.

CDP TLV "Device ID" is mapped to the LLDP "Chassis ID" field.

CDP TLV "Address" is mapped to the LLDP "Management Address" field. The CDP address TLV can contain multiple addresses,

but only the first address is shown in the LLDP neighbors table.

CDP TLV "Port ID" is mapped to the LLDP "Port ID" field.

CDP TLV "Version and Platform" is mapped to the LLDP "System Description" field.

Both the CDP and LLDP support "system capabilities," but the CDP capabilities cover capabilities that are not part of the LLDP.

These capabilities are shown as "others" in the LLDP neighbors table.

If all ports have CDP awareness disabled the switch forwards CDP frames received from neighbor devices. If at least one port

has CDP awareness enabled all CDP frames are terminated by the switch.

NOTE: When CDP awareness on a port is disabled the CDP information isn't removed immediately, but is removed when the

hold time is exceeded.

• Port Descr: Optional TLV: When checked the “port description” is included in LLDP information transmitted.

• Sys Name: Optional TLV: When checked the "system name" is included in LLDP information transmitted.

• Sys Descr: Optional TLV: When checked the "system description" is included in LLDP information transmitted.
